The present invention relates to a method and an apparatus for measuring precise high speed displacement, more specifically, to a method and an apparatus for measuring precise high speed displacement, which measures displacement of a test specimen by using a uniform intensity laser line and by using differences in a laser transmission amount according to the deformation of the test specimen, and measures a strain rate of the test specimen such as high strength fiber or the like using a high speed tensile test.
